任何人都可以帮助我吗？过去一周我正在努力扩展单元格最后我可以在其中添加子菜单。我设计了两个自定义单元格并使用 plist 我添加了菜单和子菜单。它运行良好，我添加了菜单和子菜单。现在我的问题是我想仅使用我分配的 indexpath.row 将图像和按钮添加到第 1、2、4、6 行，但是此代码将图像和按钮分配给所有行但我只想添加到第 1、2、4 行,6 只有我能做到这一点，请有人帮助我？？？

interface MyHomeView ()
{

    NSMutableArray *LeftPaneList;
    NSArray *datalist;

}
@property (assign)BOOL isOpen;
@property (nonatomic,retain)NSIndexPath *selectIndex;
@end

  - (void)viewDidLoad
{
    [super viewDidLoad];


    NSString *path  = [[NSBundle mainBundle] pathForResource:@"LeftPaneMenuList" ofType:@"plist"];
    LeftPaneList = [[NSMutableArray alloc] initWithContentsOfFile:path];



    self.isOpen=NO;

 }


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return [LeftPaneList count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (self.isOpen) {
        if (self.selectIndex.section == section) {
            return [[[LeftPaneList objectAtIndex:section] objectForKey:@"SubMenu"] count]+1;;
        }
    }
    return 1;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{




    if (self.isOpen&&self.selectIndex.section == indexPath.section&&indexPath.row!=0) {

        static NSString *CellIdentifier = @"MyHomeViewCell2";
        MyHomeViewCell2 *cell = (MyHomeViewCell2*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

        if (!cell) {
            cell = [[[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil] objectAtIndex:0];
        }
        NSArray *list = [[LeftPaneList objectAtIndex:self.selectIndex.section] objectForKey:@"SubMenu"];
        cell.name.text = [list objectAtIndex:indexPath.row-1];



        return cell;


   }

    else
    {
        static NSString *CellIdentifier = @"MyHomeViewCell";
       MyHomeViewCell *cell = (MyHomeViewCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (!cell) {
            cell = [[[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil] objectAtIndex:0];
        }
        cell.tag=indexPath.row;


        NSString *name = [[LeftPaneList objectAtIndex:indexPath.section] objectForKey:@"MenuName"];

cell.MyHomeMenuLabel.text = name;
        return cell;




}
}

这是原始的o / p！在此处输入图像描述

但我想要这样的o/p在此处输入图像描述

谁来帮帮我？？

您需要先指定，IndexPath.section然后您可以使用IndexPath.row以下示例进行检查：-

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell;

    if(indexPath.section==0)
    {
        if(indexPath.row==0)
        {

           cell = [tableView dequeueReusableCellWithIdentifier:@"CellWithButton" forIndexPath:indexPath];
        }
        else if(indexPath.row==2)
        {
          cell = [tableView dequeueReusableCellWithIdentifier:@"CellWithButton" forIndexPath:indexPath];

        }
        else if(indexPath.row==2)
        {
          cell = [tableView dequeueReusableCellWithIdentifier:@"CellWithButton" forIndexPath:indexPath];

        }
        else if(indexPath.row==4)
        {
          cell = [tableView dequeueReusableCellWithIdentifier:@"CellWithButton" forIndexPath:indexPath];

        }
        else if(indexPath.row==6)
        {

          cell = [tableView dequeueReusableCellWithIdentifier:@"CellWithButton" forIndexPath:indexPath];
        }
        else
       {
         cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
       }
    }

}

一种简单的方法是在情节提要中设置 2 个不同的动态原型单元，每个单元都有自己的标识符。在 cellForRowAtIndexPath 中：根据 indexPath 将正确类型的单元格出列。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell;
    if (indexPath.row = 1 || indexPath.row = 2 || indexPath.row = 4 || indexPath.row = 6){
        cell = [tableView dequeueReusableCellWithIdentifier:@"CellWithButton" forIndexPath:indexPath];
    }else{
        cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
    }

当您使用dequeueReusableCellWithIdentifier:方法时，它只会将索引路径 2、4、6 等处的单元格提供给 tableView 中的其他单元格。而是使用数组来存储您的单元格，然后从数组中检索它。然后你可以使用 indexpath.row
